Prisms shows white light (treated for the sake of simplicity as a mixture of seven sharply-defined colours) refracted by a ring of rotating prisms. The optical properties of the prisms are chosen so that one of the wavelengths will be refracted around the ring when the prisms are correctly aligned.
